-- 130 jThe embodiment illustrated is -an improvement on the shipping jacket disclosed'inthe patent to Kidwel-l 1N6. 1,587,655. The :form shown inFigs. 1', 5 and 6 comprisess'idelan'd end walls: 10 and 1 1 respectively, to? which is 35 secured a bottom 12, as will later be explained in detail, the whole forming a jacket which "is divided by partition members 13 to'form series or compartments 1 1.1 ln'thenpresent instance each of" these compartments,-as

" shown in Fig.6, is-adapted to hold three. ice

cream'cans orcontainrs; i Each of these compartments ispreferably 'supplied with an individualcover 15 in the form of a pad construct-odeswill later'be 45 explained, and which is carried on a flexible 'hinged member lfias of canvas, duck, arid :the like. These padsfitisnugly into the top 'oi' the compartment, andwhenrclos ed are covered over by top fiaps 17,- 18, which are made up of canvas, or the like between whicht-is a suitable insulating medium, the whole being'quilted or pocketed to retain this insulatmg medium in place 'and'prevent its shiftingl'; Suitable straps or fasteners as 19 retain these fiapsin place. i 1 The sidewalls 11'-are made up. of spaced inner. and outer envelopes 20, 21which are preferably woven fabric, such as canvas, duck treated to render it moisture and mildew proof. These envelope'shave vertically extending strips 220i the samefabric sewed therebetween so as to provide a series of vertically extending. pockets 23.' These pockets are closed at the top,-and the jacket is invertedandthese pockets are filled from the bottom after the manner disclosed in the .Kidwell patent I supra,-- preferably with ground cork 24, or a similar heat insulating material} The partition members 13' are sewed into the end" and side walls preferably prior to filling the pockets in the side walls, the pock etsin the partitions then being: filled at'the same time. Referring now to Fig.1, as the operation of filling these pockets nears completion, an upper bottom member 25 con sisting preferably of a piece of wood, slight- 'ly longer andslightly wider than the interior of the finishedfcompartment 14, is inserted between the inner envelope of the side andendwalls' and theTenvelope13F "of the partition 13. These envelopes are then drawn tightly around the bottom' member and firmly secured thereto as by means of nails 26,

-or the like.- VVith the upper and bottom members thusse'cu'red in place the operation of filling the space with the ground cork 24 is fthen cont-inued, and a layer ofthis ground corli 27 is then-preferably spread over the inembers' 25, as-shown :in Fig; 1, after which a lower bottom member 28 substantially the is'izeirof th'e shipper is placedoven the layer of cork '27l-andwithin the outer envelope 21. This envelope is then drawn tightly around and over the bottom member 28', afterwhich :9

Casters,

Straps and buckles, (not shown) or other suitable fastenings, serve to hold the cover in place. These may be located around the sides and ends. Each coveroverlies a lineof:

ice cream containers A, B, C, ig. Thus to get at the containers A the cover .33 is folded back, thereby rendering access'to these containers easy without at the same timeun covering theremaining ice cream containers, as those of the linesB, C which still remain -co vered. After' the containers of the line A have been removed, thecovers33, 34"are then rolled back thereby uncovering the similar line of containers, and so on. e r

"InFig. 3 is shown still another modificationof the invention,in which each compartment is provided with spaced metal linings 36 and 37 which are preferably rectangular in form to better accommodate the packing of icecreamlbricks, each of which is enclosed in its own paper or metal carton. These bricks,'-however, are not shown: Themetal linings-- '36, 37 are separated and held in spaced relationship by means of guide members 38, 39 which form a. channel in which may be inserted a'brine pad 40; This brine pad is shown in 4c,and consists of a metal containerfilled witha solution which will freeze only at low temperature.

In use'these brine pads are cooled to a temperature nearor below zero Fahrenheit, which is isuflicient to freeze them solid. In this condition they are inserted in the jacket and serve to keep the bricks. of ice cream frozen'while in this container for a very con siderable period of time, even though the container is subjected to quite high temperature. If desiredfthese brine pads'can be made longer, as shown at 40 in the right-hand end of Fig.3. In this form they substantially surround't-heinner metal lining 3 7 and replace the guides or spacers.

Referring to Fig. 1, it'will be" understood that the space 27 may: be omitted and the upperand lower bottom members 2'5, 28 brought together. Thesemembers may, if desired, besecured together topreventtheir shifting "undernconditio'ns offlhea'vy use. 'Moreover, the above construction, as well as that'of Fig; 1, is applicable'to a shipping acket adapted to hold a .single .ice cream containen: i.' 1 i 1 Thus itwill be seen that a" very simple and efiicient form of shipper is provided, and one which can 1 be, efliciently and "economically manufactured. The side walls of this shipper are self-supporting, and the continuous side f, compartment 'adapted tohold a single can,

or one having many compartments, and those in. whlch each compartment is adapted to hold one'or more ice cream contamers. One

advantage .ofthe-large shipper illustrated in" Fig. 6, for example, is that several cans of icecream tend to keep each other cold, thereby adding to its efficiency. p I

While I have shown and described but a few embodiments of my invention, it is to be understood that it is capable of many modifications Changes, therefore, in the construction and arrangement may be made which do not" depart from the spirit and scope of the invention as disclosed 'in the appended claims.

I claim: 1. A heat insulating shipping jacket comprising side walls made up of spacedinner and outer fabric envelopes with interconnecting members forming longitudinal pockets in which is packed heat insulating material, and a bottom comprising upper and lower rigid spaced members connected respectively to the inner and outer envelopes and providing a space communicating'withthe spaces in the sidewalls and filled with a heat insulating material. 2. A'heat insulating shipping jacket comprising sidewalls made up of spaced inner and outer woven fabric envelopes with interconnecting members forming longitudinal pockets in which is packed finely divided cork, a bottom comprising upper and lower wooden spaced members connected respectivelyto the inner and outer envelopes and providing a space communicating with the pockets in the side walls and filled with'finely divided cork, and a cover therefor. Y 3; A heat insulating multi-compartment shipping jacket comprising side walls and cross partitions made up of spaced inner and outer woven fabric envelopes with interconnecting members forming longitudinal pockpartment and the lower bottom member being continuous.

4:- A heat insulating shipping jacket comprising side walls made up of spaced inner 5 and outer woven fabric envelopes with interconnecting members forming longitudinal pockets in which ispacked finely divided heat insulating material, a bottom comprising upper and lower spaced members connected respectively to the inner and outer envelopes and providing a space communicating with the spaces in the side walls and filled with a finely divided heat insulating material, spaced metal linings, cooling means insertable between said linings, and a cover for said jacket.

5. A heat insulating multi-compartment shipping jacket comprising side walls and cross partitions made up of spaced envelope members, and a bottom member comprising upper and lower rigid members connected respectively to the inner and outer envelope members and providing a space between the rigid bottom members communicating with the space in the walls and partitions for the reception of a heat insulating material, the upper bottom members being individual to each compartment and the lower bottom member being continuous.

6. A heat insulating multi-comp'artment shipping jacket comprising side walls and cross partitions each made up of spaced inner and outer fabric envelope members, individual rigid bottom members connected to the inner envelope members of each compartment, and a rigid bottom member for the jacket connected to the outer envelope members of the side walls and spaced from the bottom members of said compartments, whereby to provide a continuous space about the sides and bottoms of said compartments for the reception of a heat insulating material.
